kernel: delete Linux 5.4 config and patches

As the upcoming release will be based on Linux 5.10 only, remove all
kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

-Subject: [PATCH] MIPS: uasm: Enable muhu opcode for MIPS R6
-
-Enable the 'muhu' instruction, complementing the existing 'mulu', needed
-to implement a MIPS32 BPF JIT.
-
-Also fix a typo in the existing definition of 'dmulu'.
